- Abstract
- This paper presents the rhombic slot antenna that has a broadband characteristic by using a low cost foam-substrate. The feed line is embedded in the middle of the triplate to prevent unwanted and spurious radiation. The proposed rhombic slot antenna has a rectangular patch with supplementary section to improve the impedance bandwidth performance. Experiments using a 2/spl times/1 array antenna are performed to validate the simulation. A bandwidth of 40% can be achieved. The electrical characteristics of the proposed antenna make it attractive for use in satellite communications.
